We tasted 3 undisclosed G&M war time bottles and deemed this to be Macallan. If it is Macallan it was possibly the saltiest one we've encountered. As salty as a Talisker or Caol Ila even! Big Mac mustard and meaty flavours, tarragon. Very very in fact dangerously quaffable! Score may bump up a bit with some oxygen in the bottle.
